Internal Reset.
0 = Normal operation.
1 = Reset of all internal logic. Output tristated during reset.
Upon completion of internal logic reset, RST_REG is internally reset to zero.

New frequency Applied.
Alerts the DSPLL that a new frequency configuration has been applied. This bit will
clear itself when the new frequency is applied.
Freezes the M Control Word.
Prevents interim frequency changes when writing RFREQ registers.
Freezes the VC ADC Output Word.
May be used to hold the nominal output frequency of an Si571.
Always zero.
Recall NVM into RAM.
0 = No operation.
1 = Write NVM bits into RAM. Bit is internally reset following completion of operation.
Note: Asserting RECALL reloads the NVM contents in to the operating registers without
